+## Prerequisites
+
+To enable load balancers to be deployed to the [China Network](/china-network/), your zone will need to meet the following two criteria:
+
+1. A valid [ICP license](/china-network/concepts/icp/) for the zone in question.
+2. The zone must be provisioned with access to the China Network.
+
+Once these two criteria are met, create a load balancer by sending a POST request to the following endpoint. To deploy to the China Network, the `networks` array in the API call must contain `jdcloud` as a value in addition to `cloudflare`. Refer to the [Cloudflare API documentation](/api/operations/load-balancers-create-load-balancer#request-body) for details on the required fields and their formats. When selecting a region for pool health checks, `China` is now available to be selected in both the dashboard and API.
+
+```bash
+https://api.cloudflare.com/client/v4/zones/{zone_id}/load_balancers
+```
+
+## Limitations
+
+Load balancers deployed to the China Network currently have the following limitations: 
+
+1. Only cookie-based session affinity is supported.
+2. Private network off-ramps (Tunnel, GRE, IPsec) are not supported.

+When selecting **All Data centers** or **All Regions**, you have the option to exclude China Network data centers from these health checks. If you choose to exclude them, Cloudflare will not send health check requests from these data centers, and they will not impact the global health status of your endpoints.
